If you pull the motor cover you can get to the rps. Then take the rps on and off about 5 times to remove a factory coating that keeps it from making the contact that it needs. For some reason the machine will work fine for several months after purchase before this occurs. After you do this it works fine. F50 f51 f70 codes
